Sudden persistent hip pain, avascular necrosis is it? To ischemic necrosis of the femoral head from less than 24 hours. Avascular necrosis of femoral head due to various reasons dominate the destruction of the blood circulation of the blood vessels, bone tissue within the femoral head and the death of nutrient supply are not a disease.
The bone tissue necrosis occurs quickly, there is no blood supply from blood vessels into the death of bone less than 24 hours. Since the destruction of bone tissue, when the necrotic area of the larger, and the residual normal bone structure can not function to maintain the femoral head, femoral head collapse occurs, the passage of time along with changes in the hip joint morphology, and thus the loss of the normal hip joint structure and function.
Occur in patients early thigh pain, hip deep in pain, or pain in front thigh, and even knee pain. The pain was insidious, activities obviously have some relief after rest, pain during the night stand. After a period of time many patients sudden pain relief, fracture of the femoral head is there to increase the bone due to pressure to ease. But with the progress of the disease, collapse of femoral head deformation, the pain again, and continued to increase, the activities of the hip is getting worse, and finally complete loss of function of the hip.
Hip pain is not always in the orthopedic treatment of femoral head necrosis in patients with a considerable number of patients were misdiagnosed as avascular necrosis. Is most likely to be misdiagnosed due to hip dysplasia hip pain, osteoarthritis and ankylosing spondylitis, there are the hip bone and osteoporosis.
Is the number one cause of alcohol, according to statistics, causing avascular necrosis of the first major cause is alcohol abuse, accounting for non-traumatic femoral head necrosis 40%. Drinking a large amount of these patients, more than three hundred forty-two drank alcohol, even drink wine 1 kg. Moreover, their history of drinking in 10 years. The second largest cause is the use of steroid drugs (people said hormone), about 30% of these patients. If both the history of alcohol and steroid use in patients, their relatively small amount of alcohol consumption and hormone use can lead to disease. Other rare factors of gout, such as caisson disease, and after radiotherapy.
How treatment of avascular necrosis of femoral head necrosis if the area is less than 25% (magnetic resonance imaging and computing), necrotic area rarely collapse, without treatment. If the necrotic area of more than 50%, almost all patients will appear collapse of the femoral head, it is recommended as soon as possible to a regular hospital treatment. In addition, when most patients come to hospital for treatment of femoral head collapse has occurred, such cases are not satisfied with the treatment effect will be only through the artificial joint replacement surgery to relieve pain and improve function. Key
Avascular necrosis of the first symptoms appear is pain, pain around the site is the hip, thigh, or knee front. Avascular necrosis of the knee pain caused by what?
Apart from avascular necrosis of hip pain, but also appears below the knee and inner thigh pain, which is nerve conduction at work. Around the hip joint is associated with two sets of nerves: the femoral nerve in front of, inside of the obturator nerve. These two branches of lumbar plexus nerve is one of the components.
Avascular necrosis of knee pain caused by what reasons:
Femoral head on the femoral nerve from lumbar 2 to lumbar 4 (L2 ~ L4), the largest branch of lumbar plexus. In the psoas muscle and the armpit down between lumbar, inguinal ligament below, shares in the lateral femoral triangle, and then dominated the quadriceps and the separation of many branch sartorius muscle and the thigh muscles in front of the regional organization. Obturator nerve origin in the lumbar 2 to lumbar 4 (L2 ~ L4), the medial edge of psoas muscle into the small pelvis, move down along the pelvic sidewall, through the medial shares closed that inner thigh. Since then divided into two:
1, the muscular branches:
Mainly dominated adductors, the inner thigh muscles, including the bone thin muscle, long adductor muscle, pubic muscle, adductor muscle. Mainly from the pubis and ischium, beyond femur.
2, skin support:
Mainly in the lower part of the medial aspect of thigh skin.
Due to the above from the femoral nerve and obturator nerve near the hip, when lesions appear hip, can stimulate the nerve conduction through the emergence of thigh and knee pain, especially the role of the obturator nerve even more. Because it is the role of nerve conduction, therefore, not only is there avascular necrosis of the knee pain and hip joint tuberculosis, congenital hip dislocation, can such a situation occur.
Described above, avascular necrosis of knee pain caused by any reason, to avoid the injured limb weight-bearing femoral head necrosis, the disease caused by complete recovery time as ordinary people (magnetic resonance imaging or bone scan with the film completely normal) before loading.
Early symptoms of ankylosing spondylitis:
The lumbar and sacral parts of the pain and stiffness associated with lower back of a sense of the majority, such a rigid sense of the morning was clear after the event can still ease through, but also to the knee, ankle, heel, sciatica onset, Early diagnosis, early treatment, to improve the cure rate and reduce morbidity, it is very important;
Medium-term symptoms of ankylosing spondylitis:
Appear lower back or lumbosacral pain, lumbar morning stiffness, increased resistance spread upward from the lumbosacral pain intensified, limited spinal stiffness, easy fatigue, weaknes
Late symptoms of ankylosing spondylitis:
Have increased lumbosacral pain, spinal pain, severe joint pain accompanied by the body, the pain was continuous uninterrupted pain; general weakness, weight loss, muscle atrophy or partial disappearance of the performance of organ dysfunction; kyphosis, spinal mobility, disappeared, Some of the difficulties of this treatment, even if cured, will leave after-effects, so patients with ankylosing spondylitis, early diagnosis, early treatment, accurate treatment is most critical.
Master the clinical symptoms of ankylosing spondylitis, I hope in the treatment of patients with symptomatic treatment further, to avoid improper selection of treatment methods miss the best timing of treatment, increased patient pain and the burden of suffering in the early detection of symptoms of ankylosing spondylitis timely treatment after treatment, to take responsibility for their own.
